JamesF Posted May 27, 2013 Share Posted May 27, 2013 For kicks and giggles last night whilst I was waiting for the Moon to climb above the roof of the barn I swung my 127 Mak over to Hercules and ran a few capture runs on M13 with my (unmodded) 450D. Perhaps not the best of targets given that area of the sky was clearly affected by glare from the Moon, but it was one I knew I could find easily with the Mak. The OTA is mounted on an old Skysurfer 2001 EQ3-2 with the aftermarket motor drives and aluminium tripod (which no longer has stones in the eyepiece tray since I found some old weights from a long-case clock to replace them) and there's no guiding or anything like that so I wasn't expecting miracles. Sure enough I had to throw away perhaps as many as half of the subs that had been affected by "wobbles", but I managed enough to stack, so here it is.12 subs of 45 seconds plus darks, unmodded 450D & 127 Mak, stacked with DSS and tweaked with Photoshop.James Link to comment Share on other sites More sharing options...
fwm891 Posted May 27, 2013 Share Posted May 27, 2013 Great result James. You could try reducing individual exposures a little and go for more subs, that may help with the success rate? Link to comment Share on other sites More sharing options...
Gina Posted May 27, 2013 Share Posted May 27, 2013 Amazing considering the kit used Link to comment Share on other sites More sharing options...
JamesF Posted May 27, 2013 Author Share Posted May 27, 2013 Great result James. You could try reducing individual exposures a little and go for more subs, that may help with the success rate?I did have a run of 30 second exposures, but they didn't seem to be a huge amount better. I think the mount is perhaps just showing its age.James Link to comment Share on other sites More sharing options...
JamesF Posted May 27, 2013 Author Share Posted May 27, 2013 Amazing considering the kit used Not the most suitable choice of imaging gear, I admit, but it was all set up and a bit of practice with focusing and so on never did anyone any harm. It looks like the sort of target that would lend itself to long focal length imaging, but a better mount and guiding are probably desirable James Link to comment Share on other sites More sharing options...
nightfisher Posted May 27, 2013 Share Posted May 27, 2013 James, you have done extremely well to get such a pleasant image with the mount and mak, be proud of that, i see on abs there is a HEQ5 going at a rather good price near you Link to comment Share on other sites More sharing options...

t_ilan_s Posted May 28, 2013 Share Posted May 28, 2013 Great image and tracking. 45 second for the EQ-3 is superb, I can't get 15 second with the EQ-5 . Link to comment Share on other sites More sharing options...

JamesF Posted May 29, 2013 Author Share Posted May 29, 2013 nice one!would like to see m81/82 with it I'll see if I can give it a go next time we have a clear night. Unfortunately the field of view will be insufficient to fit them both in the same frame. I think the DSLR sensor can cover a patch of sky about 0.5 x 0.85 degrees and they're about a degree apart.James Link to comment Share on other sites More sharing options...
tonedeaf Posted May 29, 2013 Share Posted May 29, 2013 oops....it was just a joke (ok maybe a bad one)got the same problem regarding the FOV...want to try one of these with my qhy5II as a test with my ed80 Link to comment Share on other sites More sharing options...
JamesF Posted May 29, 2013 Author Share Posted May 29, 2013 Well, you never know until you've tried it Globs are probably easier targets I have to say...James Link to comment Share on other sites More sharing options...
